[QUOTE="dok7mm, post: 1359631, member: 90080"] #1 You can use jam, or you can run a .284 mandrel into the necks of your .270 necks. Then you can use a .270 bushing die to progressively size down the neck until your bolt will close, with some pressure, in your rifle's chamber. This will give you a false shoulder on the rear 1/4 or so of your .270 neck and will hold the case firmly in your chamber for fire forming to A.I. Just start by using the bushing to reduce 1/2 of neck, or so, and try chambering. Keep adjusting bushing down in increments, until case will chamber, with some bolt pressure. Tighten die and run all your brass, and you're ready to load and form. Annealing always helps. [/QUOTE]
